There are a couple of workarounds. One is to look into the configuration. See the Pasti section of Steem.ini and it would be obvious. Only issue here is that it might not be necessarily updated from the current state (but you can force an update it if you want).

The other is to inject some kind of ACSI command in the DMA channel to see if there is something. But that looks a bit ugly for a workaround

Anyway, let me know what you need and I'll implement something in the next update (that hopefully would be released shortly).

I'd like to be able to check in config info if the enable box of hard disk config is checked.For some reason STE TOS is slow when checking ACSI drives. One shouldn't disable it if an ACSI drive is actually used. In Steem I can check its native ACSI option, but when Pasti is enabled, we're forced to keep slow TOS.It's not very important.

I don't think that STE TOS, so 1.06 and 1.62 are slow in it. With real SW it works as fast as in other TOS-es. + it is most likely same as in TOS 1.04.So, may be just something in emulation (chain) .

Famous Schrodinger's cat hypothetical experiment says that cat is dead or alive until we open box and see condition of poor animal, which deserved better logic. Cat is always in some certain state - regardless from is observer able or not to see what the state is.
